The present disclosure provides a backlight module and a display device. The backlight module includes a control circuit, a power chip, and light emitting devices. The control circuit include a control signal input terminal, and when the control signal input terminal is in a suspended state, the control circuit can output an enable signal. An enable pin of the power chip receives the enable signal, so that the power chip controls an output of a power supply voltage under a control of the enable signal. The light emitting components receive the power supply voltage, and are driven by the power supply voltage to emit light.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The backlight module of claim 1, wherein the second control module further comprises a fifth resistor, and the fifth resistor is serially connected between another of the source and the drain of the second transistor and the enable signal output terminal.
